CPUZ shows 4600MHz and 2 physical cores + 2 HT virtual cores utilize status.

After installing 9600GT, it increases 30W in standby mode.

It’s still very green.

When using built-in GPU, 4.5GHz full speed power consumption is 135W and default clock, 3.33GHz full speed power consumption is 83W.

You can see the power consumption rise up obviously after OC.

Especially for CPU with HT technology, full speed will make temperature and voltage be much higher.

GIGABYTE H55M-USB3

Good

1.With GIGABYTE 2oz, USB 3.0

2.One of few H55 products that supports dual PCI-E CrossFire

3.Wide BIOS voltage range, frequency range and rich BIOS features.

4.CPU OC range is good. 200/1600 ratio can rise CPU to 218MHz

5.External SATA chip to make up H55 without RAID

6.H55 overall power consumption is low

Weak

1.There are only two 4Pin FAN connectors.

2.During OC DDR3, the compatibility needs to improve

3.As Intel design structure, built-in GPU in i3/i5 CPU, the DDR3 performance is not outstanding.

Still remember several surreptitious prerelease H55 products by 8th Jan? The price are all above 4000NTD, around 125USD.

After official launch, many models in the market and the price drops to 3300~4300NTD, around 103~135USD.

For CPU price, most acceptable SKU are Pentium G6950 and i3-530.

Through the market price adjustment, users can accept this price range.

Not just see higher CPU and H55 MB price.

It will make many users who look for Intel Clarkdale platform hang back.

GIGABYTE H55M-USB3 market price is around 4100NTD, 128USD.

The lower version is GIGABYTE H55M-UD2H and price is 3700NTD, around 115USD.

Two H55 boards price gap is not big. The main difference is NEC USB 3.0 chip. You can pick up the suitable one after consideration.

The latest Intel All in one platform supports new manufacturing CPU + GPU design, and also make the price be higher.

Even though H55 MB price is reasonable now, CPU price still need to be lower to reach mainstream segment.

GIGABYTE H55M-USB 3.0 has good spec, OC ability and acceptable price segment.

This is my 5th P55+2nd H55 review in LGA1156 platform.

I hope it can help the users who would like to purchase H55 board can refer to my review. Thanks:) ?

CrystalDiskMark reading is 152.4 Mb/s and writing is 156.4 MB/s

FDEBENCH reading is 148 Mb/s and writing is 123 MB/s

USB 3.0 bandwidth break away from the limitation, 30~35 MB/s speed of USB2.0.

For users who using 2.5 or 3.5 inch external HDD box, they can get much higher speed acceleration.

Precondition is waiting for USB3.0 products become more popular, more users can enjoy the high performance from new technology.

As H55 doesn’t support RAID, I changed to use single SDD to test transfer rate.

CORSAIR CMFSSD-128GBG2D official spec is 220/180 MB/s

ATTO DISK Benchmark over 64k test, the max reading is 234 MB/s and writing is 188 MB/s

CrystalDiskMark reading is 220.4 Mb/s and writing is 178.2 MB/s

FDEBENCH reading is 214 Mb/s and writing is 182 MB/s

CORSAIR top SSD performance is extremely high. Even it is MLC, the performance is close to SLC.

Back to H55 chip, the HDD transfer ability is around 3% lower than X58/P55. It’s acceptable range.

32nm manufacturing can make dual core CPU clock be OC to higher.

This Core i5-660 quality is not better than 661. It needs 1.360V to reach 4.6GHz.

Of course, if you use original Cooler to OC, you need higher voltage to ramp up the speed.

Rising up the CPU voltage to achieve 5GHz in air cooling.

i5 660 GPU OC range is around 733~920MHz. The 661 is about 933~1200MHz.

Comparing to these 2 SKUs, I think 661 GPU is better picked SKU for higher clock version. The 3D performance is also higher.

After last Clarkdale review, some readers asked for more test in GAME section. This review will add two 3D games test.

If this platform is for worksheet only, Clarkdale 3D performance can meet most entry 3D software.

Using 9600GT to compare 3D performance

3DMARK2006 => 10937

In USA, some readers would like me to compare Clarkdale with 9500GSO.

Unfortunately, I only have 9600GT, so I just test 3DMARK2006.

Also can let you know mainstream VGA and built-in GPU performance gap.

For higher 3D performance request, you can install additional VGA card to enhance overall 3D performance.

Intel Core i5-660 default performance is close to i5-661.

The main difference is 3D performance which caused by clock. However, the performance is not big different.

DDR3 performance is the key weakness of Clarkdale platform.

Intel builds in GPU into CPU and this structure lower the memory controller’s performance...

As 32nm Clarkdale CPU and H55 DDR3 bandwidth, it’s not much higher than LGA775 or AM3 platform.

H55M-USB3 uses 4 phase PWM design. It is mid range components in H55 MB.

USB 3.0 chip is NEC D720200F1

Also using 3x USB power design which each USB port had independent chip to supply voltage. It’s 3 times current more.

It can avoid access problem for external devices power shortage.

H55 chipset heat sink

Due to H55 heat is not high, it doesn’t need big surface heat sink.

According to Intel UMA chipset, the 3D performance was falling behind AMD.

Even Intel last generation G45 chipset, the 3D performance still cannot compete with his competitor.

As Clarkdale platform launched, Intel royalty customers will look forward it.

All users can find the price in internet and the Clarkdale platform price is still high now.

Clarkdale structure is different with the chipset controller stage. Intel builds in GPU into CPU this time.

It lets users misunderstand the 3D performance will be improved dramatically. Even some of my friends also think in this way.

Actually, my last Core i5 661 review has showed the Clarkdale 3D performance just catch up AMD 785G.

It’s been long time that Intel IGP products 3D performance is far away behind. At least Clarkdale platform is same as AMD IGP products.

Before launching H55/H57, I think this is new segment for all MB makers well preparing for.

This time, the review board is GIGABYTE latest GA-H55M-USB3.

GIGABYTE is one of the three MB brands.

Of course, this time they will provide many H55 models for choice.

H55M-USB3 is with latest USB 3.0. It should attract many users who look for latest technology.

Let’s start with MB package.

Keep GIGABYTE consistent design style. Using white color for back and add in spec and features wording.

2oz PCB design, USB 3.0 spec are this H55 model key features.

It bundle with manual, driver CD, Smart 6 user guide, quick installation guide, cables and I/O panel.
